Today, Resident Evil 6 comes to the PC, and it’s bringing with it some exclusive content. This includes an exciting — and free — Resident Evil 6 x Left 4 Dead 2 crossover that infuses the PC version of RE6 with the cast and a couple of the enemies from L4D2. Coach, Nick, Ellis and Rochelle will be playable in the Mercenaries No Mercy mode, where the Witch and Mini Tank will appear as enemies.

The crossover begins on April 5, but you can purchase Resident Evil 6 right now on PC for #29.99 (€29.99/£19.99). See the crossover in action after the break, along with a fresh batch of screenshots from the Onslaught mode.
